I don't like the idea of banning secret societies because, besides it going against my libertarian values, it would be impossible to enforce. How can one prevent people from meeting in secret? Would one have to register any private meeting? It would just drive it underground, or there would be open meetings where all the stuff that doesn't necessitate secrecy is discussed and 'social events' where groups of 'friends' get together in private.
Then one has to define exactly what a secret society is?
The masonic movement is a well defined example, it has its rituals, dress code, bank accounts and so on. By all these features it can be recognised as an entity and the rest of society can approach the organisation with reasonable knowledge of what it is dealing with, although the extent of its influence can never be precisely pinned down.
This is to be compared with secrecy within society. In this scenario there are unwritten rules by which society conducts itself and it has the potential to be as equally corrosive as proclaimed groups. Here in Ireland we have an underlying layer of corruption that we all know about but haven't the interest or will to address properly. Indeed, many will see it as a warm characteristic of Irish life, just so long as it does not become too blatant with brown envelopes flitting from pocket to pocket at the Galway races. At a lower level we have family favours, nods and winks, unspoken 'suggestions', jobs for the boys and so on.
This is by no means unique to Ireland, whether we are any better or worse than other countries is an endless debate. Moving to France, for instance, is a pointless exercise unless you have your own personal wealth or a job you can take with you, because you won't be given one when you arrive, although that is never publicly stated.
Whether a defined organisation or a loose collection of unwritten rules it is all tribal in origin. The British express their tribal affiliations through their attachment to a sporting cause or other area of interest. The football clubs are the usual example offered. Out here in the wilds of rural Ireland it is the local GAA and county boundary which define ones identity, and to many people that is important, but not as important as family connections, which is the ultimate secret society, but impossible to control unless instructed to park granny by the window at Christmas.......
